A hotspot is a satellite image pixel with high infrared intensity, indicating a heat source.
Hotspots from known industrial sources are removed; the remaining hotspots represent vegetation fires,
which can be in forest, grass, cropland, or logging debris. A hotspot may represent one fire or be one
of several hotspots representing a larger fire. Not all fires can be identified from satellite imagery,
either because the fires are too small or because cloud cover obscures the satellite's view of the ground.

The Fire M3 hotspots are obtained from multiple sources:
